Access to community care for people with dementia and their informal carers : Case vignettes for a European comparison of structures and common pathways to formal care

BACKGROUND

People with dementia and their informal carers often do not receive appropriate professional support or it is not received at the right time.

OBJECTIVES

Description and comparison of common pathways to formal community dementia care in eight European countries as a part of the transnational Actifcare project.

MATERIALS AND METHODS

The German team was responsible for creating an individual case scenario as a starting point. The research teams in Ireland, Italy, the Netherlands, Norway, Portugal, Sweden, and the United Kingdom were then asked to describe a common pathway to formal dementia care by writing their own vignette using the provided individual case scenario.

RESULTS

A transnational qualitative content analysis was used to identify the following categories as being the most important: involved professionals, dementia-specific and team-based approaches, proactive roles, and financial aspects. General practitioners (GPs) are described as being the most important profession supporting the access to formal care in all the involved countries. In some countries other professionals take over responsibility for the access procedure. Dementia-specific approaches are rarely part of standard care; team-based approaches have differing significances in each of the countries. Informal carers are mainly proactive in seeking formal care. The Nordic countries demonstrate how financial support enhances access to the professional system.

CONCLUSION

Enhanced cooperation between GPs and other professions might optimize access to formal dementia care. Team-based approaches focusing on dementia care should be developed further. Informal carers should be supported and relieved in their role. Financial barriers remain which should be further investigated and reduced.

Long-term treatment of cancer-associated thrombosis: the choice of the optimal anticoagulant

Patients with cancer-associated thrombosis (CAT) carry a higher risk of recurrence, bleeding and mortality as compared with non-cancer patients. The specific profiles of cancer patients, combining frequent co-morbidities, the use of anti-tumoral therapies and the cancer progression itself, represent a major therapeutic challenge for choosing a long-term anticoagulant treatment. This review discusses the practical basis of making a choice between the available drugs for a long-term antithrombotic strategy, linked to their pharmacology, mechanism of action, evidence of clinical benefits, and advantages and limitations in such a complex clinical context. In patients with cancer, low-molecular-weight heparins (LMWHs) are the preferred option for the secondary prevention of venous thromboembolism according to current guidelines, because their efficacy is significantly superior to vitamin K antagonists (VKAs). Even though LMWHs are effective and safe in cancer patients, they require daily subcutaneous injections, which may be problematic for a long-term therapy that may exceed 6 months' duration. Compared with VKAs, non-vitamin-K antagonist oral anticoagulants or direct oral anticoagulants (DOACs) are more target specific and do not require laboratory monitoring, whereas the oral route of administration makes them potentially attractive alternatives to LMWH. In randomized controlled trials in the general population DOACs have been shown to be non-inferior to VKAs in terms of efficacy with a lower rate of clinically relevant or major bleeding. However, given the limited number of cancer patients enrolled in these studies (with poorly defined active cancer), available trials are inconclusive regarding the usefulness of DOACs in the cancer setting. Ongoing head-to-head comparisons vs. LMWH in patients with CAT may allow an informed choice to be made regarding the DOAC option.

Reproducibility of clinical events adjudications in a trial of venous thromboembolism prevention

Essentials The reproducibility of Clinical Events Committee (CEC) adjudications is almost unexplored. A random selection of events from a venous thromboembolism trial was blindly re-adjudicated. 'Unexplained sudden deaths' (possible fatal embolism) explained most discordant adjudications. A precise definition for CEC adjudication of this type of events is needed and proposed.

SUMMARY

Background When clinical trials use clinical endpoints, establishing independent Clinical Events Committees (CECs) is recommended to homogenize the interpretation of investigators' data. However, the reproducibility of CEC adjudications is almost unexplored. Objectives To assess the reproducibility of CEC adjudications in a trial of venous thromboembolism (VTE) prevention. Methods The PREVENU trial, a multicenter trial of VTE prevention, included 15 351 hospitalized medical patients. The primary endpoint was the composite of symptomatic VTE, major bleeding or unexplained sudden death (interpreted as possible fatal pulmonary embolism [PE]) at 3 months. The CEC comprised a chairman and four pairs of adjudicators. Of 2970 adjudicated clinical events, a random selection of 179 events (121 deaths, 40 bleeding events, and 18 VTE events) was blindly resubmitted to the CEC. Kappa values and their 95% confidence intervals (CIs) were calculated to measure adjudication agreement. Results Overall, 18 of 179 (10.1%, 95% CI 6.5-15.3%) adjudications proved discordant. Agreement for the PREVENU composite primary endpoint was good (kappa = 0.73, 95% CI 0.61-0.85). When analyzed separately, agreements were very good for non-fatal VTE events (1, 95% CI not applicable), moderate for all (fatal and non-fatal) VTE events (0.58, 95% CI 0.34-0.82), good for fatal and non-fatal major bleeding events (0.71, 95% CI 0.55-0.88), and moderate for all fatal events (0.60, 95% CI 0.40-0.81). Unexplained sudden death interpreted as possible fatal PE was responsible for nine of 18 (50%) discordant adjudications. Conclusion The reproducibility of CEC adjudications was good or very good for non-fatal VTE and bleeding events, but insufficient for VTE-related deaths, for which more precise and widely accepted definitions are needed.

Improving the mix of institutional and community care for older people with dementia: an application of the balance of care approach in eight European countries

OBJECTIVES

To examine whether the mix of community and institutional long-term care (ILTC) for people with dementia (PwD) in Europe could be improved; assess the economic consequences of providing alternative services for particular groups of ILTC entrants and explore the transnational application of the 'Balance of Care' (BoC) approach.

METHOD

A BoC study was undertaken in Estonia, Finland, France, Germany, the Netherlands, Spain, Sweden, and the UK as part of the RightTimePlaceCare project. Drawing on information about 2014 PwD on the margins of ILTC admission, this strategic planning framework identified people whose needs could be met in more than one setting, and compared the relative costs of the possible alternatives.

RESULTS

The findings suggest a noteworthy minority of ILTC entrants could be more appropriately supported in the community if enhanced services were available. This would not necessarily require innovative services, but more standard care (including personal and day care), assuming quality was ensured. Potential cost savings were identified in all countries, but community care was not always cheaper than ILTC and the ability to release resources varied between nations.

CONCLUSIONS

This is believed to be the first transnational application of the BoC approach, and demonstrates its potential to provide a consistent approach to planning across different health and social care systems. Better comparative information is needed on the number of ILTC entrants with dementia, unit costs and outcomes. Nevertheless, the findings offer important evidence on the appropriateness of current provision, and the opportunity to learn from different countries' experience.

Update in urethral stents

Urethral stents were first introduced in 1988, and since then, they have undergone significant improvements. However, they did not gain a wide popularity and their use is limited to a small number of centers around the world. Urethral stents can be used in the entire urethra and for various and diverse indications. In the anterior urethra, it can be used to treat urethral strictures. In the prostatic urethra, they can be used for the treatment of prostatic obstruction, including benign, malignant and iatrogenic prostatic obstruction. Moreover, although not widely used, it can be also applied for the treatment of posterior urethral stricture and bladder neck contracture, usually resulting in urinary incontinence and the need for subsequent procedures. Our main experience are with Allium urethral stents, and as such, we provide the latest updates in urethral stents with special emphasis on the various types of Allium urethral stents: bulbar, prostatic and bladder neck stents.

abiliti Closed-Loop Gastric Electrical Stimulation System for Treatment of Obesity: Clinical Results with a 27-Month Follow-Up

Background

The aim of the study was to evaluate the safety and effectiveness of a novel closed-loop gastric electric stimulation device (abiliti^® system) featuring a transgastric sensor to detect food intake and an accelerometer to record physical activity to induce and maintain lifestyle changes to treat obesity.

Methods

In a prospective, multi-center study, 34 obese subjects (BMI of 42.1 ± 5.3 kg/m²) who passed an eligibility evaluation were implanted with the abiliti system. Safety evaluation included an endoscopic exam to assess the intragastric electrode healing. Efficacy evaluation at 1 year of therapy included weight loss, improvements in eating, and exercise behavior and quality of life.

Results

The transgastric implant controlled by endoscopy was stable for all participants. At 12 months (12 M) the mean excess weight loss (EWL) was 28.7 % (95%CI, 34.5 to 22.5 %), and mean reduction in BMI was 4.8 ± 3.2 kg/m². At 27 months (27 M), the EWL was 27.5 % (95 % CI, 21.3 % to 33.7 %). Eating behavior, evaluated by the “Three Factor Eating Questionnaire”, showed a significant increase in the cognition factor and decrease in the disinhibition and hunger factors at 12 M in comparison to baseline (p < 0.001). Participants significantly increased their weekly physical activity (p < 0.001). Quality of life was improved in 55.2 % of the patients.

Conclusions

Gastric electrical stimulation with abiliti system in obese participants is well tolerated and leads to significant 12 M weight loss, which was stable to 27 M. We suggest that weight loss is achieved due to the assessed alteration of eating behavior in particular the reduction in disinhibition and hunger, and the measured increase in physical activity.

[Computerized ranking test in three French universities: Staff experience and students' feedback]

BACKGROUND

The year 2016 will be pivotal for the evaluation of French medical students with the introduction of the first computerized National Ranking Test (ECNi). The SIDES, online electronic system for medical student evaluation, was created for this purpose. All the universities have already organized faculty exams but few a joint computerized ranking test at several universities simultaneously. We report our experience on the organization of a mock ECNi by universities Paris Descartes, Paris Diderot and Paris 13.

METHODS

Docimological, administrative and technical working groups were created to organize this ECNi. Students in their fifth year of medical studies, who will be the first students to sit for the official ECNi in 2016, were invited to attend this mock exam that represented more than 50% of what will be proposed in 2016. A final electronic questionnaire allowed a docimological and organizational evaluation by students. An analysis of ratings and rankings and their distribution on a 1000-point scale were performed.

RESULTS

Sixty-four percent of enrolled students (i.e., 654) attended the three half-day exams. No difference in total score and ranking between the three universities was observed. Students' feedback was extremely positive. Normalized over 1000 points, 99% of students were scored on 300 points only. Progressive clinical cases were the most discriminating test.

CONCLUSION

The organization of a mock ECNi involving multiple universities was a docimological and technical success but required an important administrative, technical and teaching investment.

Risk of recurrent venous thromboembolism and major hemorrhage in cancer-associated incidental pulmonary embolism among treated and untreated patients: a pooled analysis of 926 patients

ESSENTIALS: We performed a pooled analysis of 926 patients with cancer-associated incidental pulmonary embolism (IPE). Vitamin K antagonists (VKA) are associated with a higher risk of major hemorrhage. Recurrence risk is comparable after subsegmental and more proximally localized IPE. Our results support low molecular weight heparins over VKA and similar management of subsegmental IPE.

BACKGROUND

Incidental pulmonary embolism (IPE) is defined as pulmonary embolism (PE) diagnosed on computed tomography scanning not performed for suspected PE. IPE has been estimated to occur in 3.1% of all cancer patients and is a growing challenge for clinicians and patients. Nevertheless, knowledge about the treatment and prognosis of cancer-associated IPE is scarce. We aimed to provide the best available evidence on IPE management.

METHODS

Incidence rates of symptomatic recurrent venous thromboembolism (VTE), major hemorrhage, and mortality during 6-month follow-up were pooled using individual patient data from studies identified by a systematic literature search. Subgroup analyses based on cancer stage, thrombus localization, and management were performed.

RESULTS

In 926 cancer patients with IPE from 11 cohorts, weighted pooled 6-month risks of recurrent VTE, major hemorrhage and mortality were 5.8% (95% confidence interval [CI] 3.7-8.3%), 4.7% (95% CI 3.0-6.8%), and 37% (95% CI 28-47%). VTE recurrence risk was comparable under low molecular weight heparins (LMWH) and vitamin K antagonists (VKAs) (6.2% vs. 6.4%; hazard ratio [HR] 0.9; 95% CI 0.3-3.1), while 12% in untreated patients (HR 2.6; 95% CI 0.91-7.3). Risk of major hemorrhage was higher under VKAs than under LMWH (13% vs. 3.9%; HR 3.9; 95% CI 1.6-10). VTE recurrence risk was comparable in patients with an subsegmental IPE and those with a more proximally localized IPE (HR 1.1; 95% CI 0.50-2.4).

CONCLUSION

These results support the current recommendation to anticoagulate cancer-associated IPE with LMWH and argue against different management of subsegmental IPE.

[Angiosarcoma mimicking recurrent pulmonary embolism]

INTRODUCTION

Pulmonary artery sarcoma is a rare disease with non-specific symptoms. The clinical and radiological presentation can mimic pulmonary embolism with chronic thromboembolic pulmonary hypertension. Management is essentially surgical but the prognosis remains poor.

CASE REPORT

A patient presented with symptoms of pulmonary embolism. Despite vitamin K antagonist therapy, he suffered from extension of the endovascular defects and his pulmonary hypertension increased. Suspicious results of positron emission tomography suggested the diagnosis of pulmonary artery sarcoma that was confirmed by surgery. However, the outcome was unfavourable, leading to death of the patient.

CONCLUSION

This case reinforces the idea that the clinical and tomodensitometric presentations of pulmonary arterial sarcoma and chronic thromboembolic pulmonary hypertension are similar. The positron emission tomography seems to be a key to distinguishing these two diagnoses.
